periphyton

美[pərɪfɪˌtɒn] 英[pərɪfɪtɒn]

n. [生]固着生物；水生附着生物

With high adaptability, periphyton could adhere to any surface in the water. 附生藻类具有高适应性，可附著在水域任何物体的表面上。
Closely associated with the benthic community are organisms collectively called periphyton or aufwuchs. 但是当水变浅时，生物相会改变。
While the nitrogen concentration was 2 mg/ L,this effect was no significant different between the periphyton and phytoplankton. 而当氮浓度较低时(2 mg/L),浮游藻类与附着藻类对N/P的响应则没有显著的差异;
Cumulative removal ratio of nitrogen was closely related with nitrogen concentration，working time and biomass of periphyton. 附着生物对水柱中氮的累积去除率和水柱中氮的浓度、附着生物的生物量以及附着生物作用时间密切相关。
In the first cultivation stage，as relatively high concentration of phosphorus，phosphorus from water column was removed to a certain extent by periphyton. 从培养过程中水体磷的浓度变化来说，培养初期，水体中磷的浓度比较高，附着生物对其有一定的去除作用；
The present study shows that periphyton can remarkably reduce the phosphorus in stream water and thus is able to prevent water reservoirs from eutrophication when it is applied in the watershed. 由以上结果可知附生藻类具有降低营养盐至贫养程度的能力，如在集水区溪流施用附生藻，可有效降低水库优养化的发生。
